DETAILED DESCRIPTION

The present disclosure relates to application buttons, and more specifically to using tap data to modify application button size. While the present disclosure is not necessarily limited to such applications, various aspects of the disclosure may be appreciated through a discussion of various examples using this context.

To stay competitive in the digital world and retain customer loyalty, application owners and/or developers may need to continuously satisfy users by constantly making customer experience improvements on their applications (e.g., mobile applications). Improvements to applications may include an increase in application button size to allow for easier user accessibility of the applications. Typically, devices (e.g., computer system, mobile device, etc.) may display multiple application buttons at a condensed or reduced size on a screen of the device. The small sizes of the application buttons may make it difficult for a user to select the application button. Thus, increasing the button size for an application may result in an increase in user satisfaction towards the application.

The present disclosure provides a computer-implemented method, system, and computer program product to use user interaction data, including tap data, to determine a tap ratio. The tap ratio may be used to determine whether to adjust the size of the application button. Aspects of the present disclosure are directed toward using data regarding user taps, herein tap data, to select the application button to determine whether to increase a display size of the application button, either permanently or temporarily. Taps may include any method for selecting an application button on a screen of a computing device. Methods for selecting an application button may include using a mouse, pointer, finger, or any other selection technology.

When a user attempts to select the application button, the user may not always be successful. When the user is not successful in selection, particularly when the user did not tap or hit the application button, the user may have a missed tap. These missed taps and a total number of taps (herein, overall taps), including successful and missed taps, may be compared. This comparison may then be used to determine whether to increase the size of the application button.

Referring now to FIG. 1, a flowchart illustrating a method 100 for adjusting a size of an application button is depicted, according to various embodiments. In an embodiment, the method 100 is implemented as a computer script or computer program (e.g., computer executable code) to be executed by a server, such as server 220 (FIG. 2), on, or connected to, a computer system, such as computer system 200 (FIG. 2) or computer system 600 (FIG. 6). In various embodiments, the server is a computer device, such as computer system/server 602. In some embodiments, the server is a computer program or computer script.

In various embodiments, a server is configured to execute operation 110 to receive user interaction data associated with an application button. In various embodiments, the application button is an icon corresponding to an application, such as application 215 (FIG. 2). User interaction data may include at least tap data. In various embodiments, taps include one or more of: a finger tap on a touch sensitive device, a mouse click, a button click, and any other method for selecting the application button. Tap data may include any data pertaining to taps associated with an application button. In various embodiments, tap data includes all data pertaining to taps on a device, for example user device 210 (FIG. 2). Tap data may include quantity (e.g., a count) of taps, location of taps, time of taps, method of taps, etc. For example, the device may be a touch screen computer, thus a user has a multitude of methods of taps including finger tapping the touch screen and using a mouse or trackpad to tap or select the application. Tap data may include data from each of these methods.

In various embodiments, a server receives the user interaction data from an application, such as application 215 (FIG. 2). In some embodiments, the server receives the user interaction data from an application developer. The application and/or the application developer may have a button management tool, such as button management tool 217 (FIG. 2) that gathers, manages, and sends the user interaction data to the server.

In various embodiments, a server is configured to execute operation 120 to determine a quantity of missed taps associated with the application button by analyzing the user interaction data. A missed tap may be a tap at a certain distance (e.g., a predetermined distance) away from the application button or within a region separated from the application button. A region may include a surrounding area around the application button of a graphical user interface. In some embodiments, a missed tap is a tap that does not select the application button.

In various embodiments, a missed tap is determined using a buffer region outside the application button. In some embodiments, the buffer region includes any region outside of an outer boundary of the application button. The buffer region may be a region or distance surrounding the application button (e.g., surrounding area). In various embodiments, the buffer region is calculated using statistical analysis. The calculation may use a history of tap data to determine previous locations of taps, and these previous locations of taps may be used to calculate, or determine, the buffer region. In some embodiments, the buffer region is a predetermined region. The predetermined region may be selected, or set, by the button management tool. In some embodiments, the predetermined region is set by the server, or a button analytics module, such as button analytics module 225, within the server.

Once the buffer region is determined, the server may determine the quantity of missed taps by calculating a quantity or number of taps outside the buffer region, using the user interaction data. Calculating the quantity of taps outside the buffer region may include identifying each tap located outside the buffer region and computing (e.g., using summation) the total quantity or amount of identified taps.

In some embodiments, other application buttons are located near the application button (e.g., within a distance, region, surrounding area, etc.). These other application buttons may be referred to herein as nearby application buttons. In various embodiments, determining the quantity of missed taps associated with the application further includes identifying nearby application buttons, determining a nearby buffer region for each nearby application button, and calculating a quantity of taps between the buffer region and the nearby buffer regions, as well as a quantity of taps detected within a second region of the application button.

The nearby buffer regions may be determined using the same methods used to determine the buffer region surrounding the application button, as discussed herein. In various embodiments, the distance or region used to identify nearby application buttons is referred to as a first region. The second region may be a distance or region surrounding the application button, usually smaller than the first region. The first region and the second region, such as 570 and 560 respectively (FIG. 5), are further discussed herein.

In various embodiments, a server is configured to execute operation 130 to compare the quantity of missed taps to a quantity of overall taps to determine a tap ratio. The quantity of overall taps may be a total number of taps, including the quantity of missed taps, for the application button. The tap ratio may be a ratio of the quantity of missed taps to the quantity of overall taps. In various embodiments, the tap ratio may be a fraction, a percentage, or any other type of comparison.

In some embodiments, comparing the quantity of missed taps to the quantity of overall taps includes determining a quantity of buffer taps, determining a quantity of hit taps, and/or calculating the quantity of overall taps using the quantity of missed taps, the quantity of buffer taps, and the quantity of hit taps. A buffer tap may be a tap inside the buffer region. A hit tap may be a tap on (e.g., hits, touches, overlaps, etc.), or a tap that selects, the application button. In various embodiments, quantities of buffer taps and quantities of hit taps are determined using user interaction data. In various embodiments, the quantity of buffer taps, the quantity of hit taps, and the quantity of overall taps are tap data, and therefore user interaction data.

In some embodiments, calculating the quantity of overall taps includes identifying each tap corresponding to the application button and computing (e.g., summation) the total quantity or amount of identified taps. In some embodiments, calculating the quantity of overall taps includes a sum of the determined quantities of buffer taps, hit taps, and missed taps.

In various embodiments, a server is configured to execute operation 140 to determine whether the tap ratio is above a missed tap threshold. In some embodiments, the missed tap threshold is calculated using statistical analysis to determine an optimum threshold. The calculation may use a history of tap ratios for one or more application buttons. The calculation may further use a history of tap data for one or more application buttons. In some embodiments, the missed tap threshold is a predetermined, or preset, threshold value. The predetermined threshold value may be determined, or set, by the button management tool. Alternatively, the predetermined threshold value may be set by the server, or by a button analytics module, such as button analytics module 225, within the server.

In various embodiments, a server is configured to execute operation 150 to, in response to determining that the tap ratio is above the missed tap threshold, increase a size of the application button. In some embodiments, the increase in size of the application button is a permanent increase. In other embodiments, the increase in size is a temporary increase.

In various embodiments, when the increase in size is a temporary increase, the method 100 further includes detecting user selection of the application button and decreasing the size of the application button. User selection of the application button may include a user tapping, or clicking, the application button. In some embodiments, the application button is decreased to the original size, or size before the increase.

In various embodiments, the server determines that the tap ratio is below the missed tap threshold. In response to determining that the tap ratio is below the missed tap threshold, a server may be configured to leave the application button at the original size, or not change the size of the application. In some embodiments, in response to determining that the tap ratio is below the missed tap threshold, the server returns to operation 110.

Referring to FIG. 2, a block diagram of a sample computer system 200 for adjusting size of an application button is depicted, according to various embodiments. System 200 is one possible computer system capable of adjusting the size of the application button, and is illustrated for example purposes.

In various embodiments, system 200 includes a user device 210 and a server 220. In some embodiments, the user device 210 communicates with the server 220 via any suitable network (e.g., local area network, wide area network, etc.). The user device 210 may include one or more applications. The system 200 depicts user device 210 with one application 215. User device 210, however, is not limited to this depiction. Application 215 may include a button management tool 217. In various embodiments, the button management tool 217 is the button management tool referred to herein.

In some embodiments, the server 220 includes a button analytics module 225. In various embodiments, the button analytics module 225 executes the operations 110-150, discussed herein and depicted in FIG. 1.

Referring to FIG. 3, a schematic diagram of an example tap scenario 300 is depicted, according to various embodiments. Tap scenario 300 is one possible scenario illustrating taps of the application button, and is illustrated for example purposes.

In various embodiments, example tap scenario 300 includes an application button 310 and a buffer region 315. Tap scenario 300 may also include taps 312, 322, 324, 332, 334, and 336. In this example, tap 312 may be a hit tap, as it is located on the application button 310. Taps 322 and 324 are located inside the buffer region 315, thus taps 322 and 324 may be buffer taps. Taps 332, 334, and 336 are located outside the buffer region 315, thus taps 332, 334, and 336 may be missed taps.

In the example tap scenario 300, a server, such as server 220 (FIG. 2), and/or a button analytics module, such as button analytics module 225 (FIG. 2), may determine or calculate a total of three missed taps (taps 332, 334, and 336). The server and/or the button analytics module may also determine or calculate a total of six overall taps (taps 312, 322, 324, 332, 334, and 336).

Referring to FIG. 4, a schematic diagram of an example tap scenario 400 with nearby application buttons is depicted, according to various embodiments. Tap scenario 400 is one possible scenario of application buttons and taps, and is illustrated for example purposes.

In various embodiments, tap scenario 400 includes application button 410, nearby application button 420, nearby application button 430, and nearby application button 440. Application button 410 may be surrounded by buffer region 415. Nearby application buttons 420, 430, and 440 may each be surrounded by buffer regions 425, 435, and 445, respectively.

Tap scenario 400 may also include taps 451, 453, 455, 457, and 459. Tap 451 is located inside buffer region 415, thus tap 451 may be a buffer tap. Taps 453 and 459 may be located between buffer region 415 and the nearby buffer regions 425 and 445, thus taps 453 and 459 may be missed taps. In the tap scenario 400, taps 457 and 455 may not correspond to application button 410, due to distance from the application button 410 (as discussed herein), and thus may not be included in the quantity of overall taps.

In the example tap scenario 400, a server, such as server 220 (FIG. 2), and/or a button analytics module, such as button analytics module 225 (FIG. 2), may determine a total of two missed taps (taps 453 and 459). The server and/or the button analytics module may also determine a total of three overall taps (taps 451, 453, and 459).

Referring to FIG. 5, a schematic diagram of a first region 570 and a second region 560 for an example tap scenario 500 is depicted, according to various embodiments. Tap scenario 500 is one possible scenario of application buttons and taps, and is illustrated for example purposes.

In various embodiments, tap scenario 500 includes application button 410, buffer region 415, nearby application button 420, nearby buffer region 425, nearby application button 430, nearby buffer region 435, nearby application button 440, and nearby buffer region 445, from tap scenario 400 (FIG. 4), along with first region 570 and second region 560. In various embodiments, first region 570 is a region or distance near, or surrounding, the application button used to identify surrounding applications. Second region 560 may be a region or distance near, or surrounding, buffer region 415 used to identify missed taps corresponding to the application button 410. In various embodiments, first region 570 and second region 560 are determined by a server and/or a button analytics module, such as server 220 and button analytics module 225 (FIG. 2). In this example tap scenario 500, nearby application buttons 420, 430, and 440 are all at least intersecting first frame 570, thus indicating that nearby application buttons 420, 430, and 440 are nearby applications.

Tap scenario 500 may also include taps 451, 453, 455, 457, and 459 from tap scenario 400 (FIG. 4). Tap 451 is located inside buffer region 415, thus tap 451 may be a buffer tap. Taps 453 and 459 may be located inside second region 560, thus taps 453 and 459 may be missed taps, in this scenario. In this tap scenario 400, taps 457 and 455 are not inside second region 560, indicating that taps 457 and 455 may not correspond to application button 410, and thus may not be included in the quantity of overall taps.

In this example tap scenario 500, a server, such as server 220 (FIG. 2), and/or a button analytics module, such as button analytics module 225 (FIG. 2), may determine a total of two missed taps (taps 453 and 459). The server and/or the button analytics module may also determine a total of three overall taps (taps 451, 453, and 459) for application button 410.
